RE: What to map this to?

["Reeve Fritchman" <reeve@xxxxxxxxxx>]

Step 1: DMPTAP to check record length and block size.
Step 2: Copy records to *PRINT with *HEX option
Step 3: Inspect data format.  If the low-order (rightmost) zone is F/D
(mainframe uses other signs), and if the number is reasonable, it really is
packed.
Step 4: THIS IS IMPORTANT: trust no one, and trust nobody's documentation!

In ILE COBOL, "COMP" means "packed decimal"; the definition appears to be
packed 9-digit number with 0 decimals.  But 4 bytes isn't enough for a
9-digit number.

Subject: What to map this to?

I have a tape that I am being sent by a customer.  I have to input the file
and convert it to our format.

I have a record layout from our customer but it appears the file was created
with COBOL, we use RPG.

My problem is I'm not sure how to input one of the fields.  The field is
defined as positions 21-24, length 4, with a pic claus of PIC S9(9) COMP.
My COBOL is very rusty, I have looked at or written a program since college
and from my memory S9(9) would be a value of -999999999 to +999999999 ...
how does this fit into a feild of lenght 4 and how do I read this value
properly in RPG?
